What did you try so far?

If you do not keep changes after a restart then see:

• http://kb.mozillazine.org/Preferences_not_saved
• https://support.mozilla.org/kb/Preferences+are+not+saved

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

• https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Hi Bob,

You could try to reset your homepage to something else by following the instructions in this article

• How to set the home page

If that does not work it is likely that you have knowingly or otherwise installed some software extension such as a search bar (Or possibly something from a ISP or even malware) and you will need to identify and remove that.

• Remove a toolbar that has taken over your Firefox search or home page

BTW I can not see any other questions by you relating to this problem.

Post back with how you get on.

Question owner

Have tired to re set the home page several times keeps reverting back. Tried disabling toolbars but that does not work. Will keep working on it. Someone out there must have downloaded this mal ware and figured out how to get rid of it.

Thanks for the advice will keep on plugging away

Bob

1. Go to Help > Troubleshooting Information, then click on Open Containing Folder. That will open Windows Explorer in your Firefox profile.
2. Close Firefox.
3. In your profile folder, if there's a file called user.js, delete it.
4. Try resetting your home page again.

Question owner

Tried all above, still cannot get rid of http://btsearch.name/# as default home page. Will redo suggestions.

You may well have inadvertently downloaded software or even malware that is making changes to your system. if the above suggestions do not help then start looking for malware, See this post as for instructions: /questions/914980#answer-302372

Question owner

No file like that. Finally deleted firefox completely. Backed up my extensive bookmarks and could not import them. Now manually re entering them. Still have http://btsearch.name/ as home page.

ARRRRRRRGGGGGGGGHHHHHHHH

Yup, sure sounds like malware to me.

Read through this article to find the malicious software and find a tool that will help you remove it. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware

I solved this problem on my pc by uninstalling youtube downloader. restarted, then problem solved. Hope this helps others.

I tried all of the above including deleting the whole profile folder and then reinstalling Firefox and syncing with my laptop. Problem came back. Solution: I use Chrome now.

Hi geekoid,
You're replying to a thread that is over 4 months old. You should use https://support.mozilla.org/en-US/questions/new where volunteers can get more details about your setup.

Because this thread is so old and more people might start using it for their own questions, I'm going to lock it.
